COMBINED COOLER AND FILTER.

SECIFICATIQN forming part of Letters Patent No. 274,339, dated March 20,1888. Application led August 19, 1882. (No model.)

To all 'whom it may concern:

Beit known that I, SUTHERN KALFUS, of Louisville, in the county ofJefferson and State of Kentucky, have invented certain uew'a-nd usefulIm provements in a Combined Cooler and Filter; and I do hereby declarethat 'the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to malte and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

Heretofore Watercoolers with filters have been constructed with awater-drip around the outside, as vvell as disks for filtering purposes,

,in connection with filtering material, such being capable only forimperi'ectly cooling and fllteringthewater. Thedisadvantagesarising fromthe arrangement of the above devices are suchthat it is impracticable tocool and filter the water thoroughly without the use of felt or otherfibrous material around the exterior ot the cooler, as itis upon thisfibrous material the water is drawn up constantly by capillaryattraction from the saucer that holds the vessel, and as it is Wellknown that in the tropical States, Where the climate is hot, the Wateris brackish and very impure, and that it requires a iilter and cooler`that will more thoroughly cool and ilter the Water than has hithertobeen done, and to also produce a vessel or jar for preserving andkeeping cool meats, vegetables, dac., as well as to protect the contentsof the jar from insects, which are very numerous in that and othersections of the country; and to this end my invention consists in thenovel construction and arrangement of parts, whereby these defects areovercome and the Water cooled and ltered thoroughly without the use ofice.

The annexed sheet of drawings, to which reference is made, fullyillustrates my inven-4 tion, in which- Figure l represents a verticalsectional view of my improved cooler and filter. Fig. 2 is a `horizontalsectional View taken through the cover, Fig. 3 is also a horizontalvsectional view taken through the body of the' cooler, showing a planview of disk. Fig. et isa similar view to Fig. 3, showing bearings andindentations. Fig. 5 is a sectional view in modi 'tains the filteredwater.

tied form, and containing family jar or vessel. Fig. 6 is ahorizontalsection of Fig. 5, showing bottom' bearings to support inside vessel.

Referring by letters to the accompanying drawings, A designates a vesselthat forms the body of the cooler, having on its inner side lugs a, andat or near the bottom an opening, in which is placed a suitable faucet,a', and around the exterior of said vessel is Wrapped felt or anysuitable porous or fibrous material, for a purpose vhereinaftermentioned.

B B indicate perforated disks, placed one above the other and within thevessel, which are supported in position by lugs a.

C indicates a tube open at both ends, and extending from the lower diskto near the top of the vessel, for exhausting air from the lowercliarnberor compartment from which the Water is drawn.

Thepositionsot'the disks are such that the vessel is divided intochambers or compartments, in the presentV instance three, b h b2, theupperone, b, containing filtering materialsuch as sand, gravel, Src-andthe middle one, b', also containing charcoal or other good filteringmaterial, While the lower chamber, b2, con- The inside ot thiswater-compartment b2 is glazed.

D designates the lid or cover, made hollow, forming a chamber, c, andprovided with a hand-knob, c', having an opening, ci, forming a passagethat communicates with said chamber o in the lid, and the same isfurther provided with small perforations d in its bottoni, near theedges thereof, and just outside ot' the wall of the vessel, inclined soas to jet Water against fibrous covering. This lid or cover is glazed onits bottom, and has an annulns thereon, as shown in Fig. l.

E represents a saucer or pan, in the bottom of which is placed a mat,d', of flexible material, and upon which the cooler rests when placedwithin the saucer.

Having described the differentparts of Which my cooler is constructed, lwill now explain the operation.

The lid or cover is removed and the water is poured into the vessel.rihe Water then passes down through the sand and upper disk, through theperforatio is to the next chamber, thence through the charcoal andthrough the perforated disk B, and finally enters the lower on itspassage through the same.

chamber, b2, the water being iltered or purified l mat for the receptionof the water that drib- 'Ihe Water lid or cover is then filled withwater through the opening c2, and through the small perforations in thebottom thereof the water dribbles of the vessel, which keeps the feltmoist as fast as the water evaporates, and keeps the water in the vesselcool, the water dribbling over the brous material being received in thesaucer.

Fig. 5 shows the Vessel or jar slightly modied in form, the same to beused for preserv-r ing and keeping cool meats, vegetables, &c., (in thisinstance the filtering materiall isdispensed with,) and has the lugs andwrapping, as shown in Fig. 1, and the outside vessel may be constructedof stone, eartherware, or any suitable material, and is to be placedWithin a saucer and have a cover similar to the one above described. f

In the bottom of the vessel as modified I construct projections or ribse, on which rests a sm aller vessel, e', constructed of metalsuch astin, zinc, &c.-with shelves or half-perforated disks made of beech,maple, or cedar wood; or they may be made of metal, as may be found mostconvenient or practicable,form ing compartments, as shown in dottedlines, and having a suitable cover and" reversible handles secured tothe vessel.

It will be observed that in placing the one vessel within the other thedisks B B are re moved. The Water dribbling from the cover on the outervessel keeps the inner vessel cool, while the projections in the bottomelevate the inner vessel and permit air to circulate around said vessel;also, itwill be observed that the disks can be easily'removed, whendesired, by simply registering the openings e2 with the lugs of thevessel A. The mat in the saucer protects the latter and the vessel frominjury when the vessel is carelessly seated within said saucer.

Having thus described my invention, wha-t I claim as new, and desire tosecure by Letters Patent, is

l. The combination of the water cooler and filter and drip pan orsaucer, provided with a bles from the cover, and for feeding or supply-5o ing water from said pan to the felt covering of the vessel, which isin contact with the vessel and Water, all substantially as set forth.upon and saturates the felt on outside cover I 2. In a water cooler andfilter, the cover, constructed as described. provided with inclined 55perforations, each inclined toward the wall of the vessel or cooler, thevessel being provided on its exterior with a covering of iibrousmaterial, and the cover With an annulus on its under side lfor keepingthe cover in position, sub- 6o stantially as described.

3. In a water cooler and filter, the combination, with the vesselprovided with lugs and removable disks, said vessel being also providedwith upwardly-projecting ribs and adapted 65 to receive an inner vesselwhen the disks are removed, substantially as described. v

4. A filtering-vessel for water and for conserving food, constructedwith inner projecting lugs for the support of disks when used, and 7owhen removed forcenterin g an inclosinglvessel, the filtering-vesselbeing glazed to the height of the' lower water-chamber, said vesselbeing' adapted to be Wrapped with brous material, and provided with awater-ehambered lid or `7 5 cover, which is also adapted to continuouslymoisten the wrapping, in combination with an outside water-receptacle,substantially as dcscribed.

5. A filtering and cooling vessel provided 8o with .disks or diaphragms,said disks having pieces cut out of their edges to permit passage oversupportin g-lu gs, and to register with said lugs whenwithdrawn, thelugs being arranged to support the disks in position by 8'5 slightlyturning the disks, in combination with a central air-tube which forms ahandle .for raising the disks out of the vessel, as described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two 9o witnesses.
